Jerk off to whatever you like. It's your time and your penis.
Just know that it's not real. Also know that some women LOVE being treated...dirty. You have to get to know them first, though.
I'd say the vast majority of women if not every woman and I'd use the word, eh.. vulnerable. If there is one thing every man will learn in his life it's this fact. Befriending women and whiteknighting is a mistake too many young lads are making these days, it's like they don't have male groups to tell them to stop that shit. I'd reckon it's causing many problems in society too, both apparent and not so apparent.
Everything in the above reply is my opinion, from my own perspective and not representative of reality outside of my own head!
